IMPRQYEMENT INMACHINESFOR MAKlNG HoRsEs cEsq-fl Specification forming part of Letters Patent No. 182,268, dated September 19, 1876; application filed June 19,1876,

Beit known that I, CLINTON BROWNING,

of Short Creek, in the-county of Ohio and.

State of NVest Virginia, have invented new and'useful Improvements in Horseshoe-Machines, which improvements are fully setforth in the following specification, reference being had to the accompanying drawings,i'n which- Figure 1 is a top view of my improved horseshoe-machine. Fig. 2 .is a side. elevation of the same. Fig. 3 is a cross-section through the forming-wheels and the dies attached thereto. Figs. 4 and 5 are detailed-views of the blank shaping andcutting rollers, in connection with the feed-motion of the formingcylinders. Figs. 6 and 7 are detailed views of the bending-rollers and their operatinggear. Fig. 8 is a detailed view, in part section, of the guideway for-the operating-rollers of the movable dies in the bending and form ing wheel. Fig. 9 is a. transverse section through the operatingrollers of the bendinggear, together with a segmental'section of the main gear-wheel, upon the rim of which the said rollers travel. Fig. 10 is atransverse section of the sliding shanks of the above said movable dies, showing the manner of embedding them in the web of the forming-wheel." Figs. 11 and 12 are detailed views, illustrating the manner of detaching a finished horseshoe from the movabledies of the forming-wheel. Fig. 13 is alongitudinal section of one of the dies fastened to the pressure-wheel. is a transverse section of the same. is a longitudinal section of the dies on the forming-wheel. Fig. 16 is a transverse section of the same. Fig. 17- is an elevation of the die which forms the creases and prints for the holes of the horseshoe-nails.

The nature of my invention consists of certain constructions, combinations, and arrangements of parts, as hereinafterdescribed and The'object of my invention. is to make a horseshoe so complete and perfect that it is "at once a marketable article as it leaves the machine.

To enable others skilled in the art to under Fig. 14 Fig. '15

stand my invention, I will proceed to describe it sents a suitable frame, supported by legs a. Across the said frame A two shafts, B B, are embedded in bearings b b 71 b. The former, B,

being the main shaft, has a toothed gearwheel, 0, fastened to it, which'drives another gear-wheel, O, on the shaft B, of the same diameter and number of teeth. The gearwhee-l C is dri'ven'by a pinion, a on a shaft, a which receives? its power from the lineshafting of the building. TheshaftB has also a die-wheel, D, which is in contact'with another die-wheel, D, on-the shaft B, both die-wheels being of the same diameter. The shaft B has a bevel-wheel, E, which drives another bevel-wheel, E, on a shaft, F, in an inclined frame, G. The shaft Fhas a gearwheel, E, which drives another gear-wheel, H onanother shaft, H, both gear-wheel's being of the same size. Next to the said gear. wheels are two rollers--one, F on the shaft F, and the other, H on the shaft E, Fig. 4.

:The lower roller, F is provided with knifeedges,f, wherewith "it separates theiron bar placed upon it. i The periphery between the knife-edges f is not concentric to the shaft F, but of smaller radius in the middle, whereby the blank piece as for the shoes is made'broader in the middle than at both ends.

The upper roller H is concentric, and, has two side flanges, h, wherewith to keep the iron bar in position while being rolled. The lower roller F has two corresponding receding flanges, f, to strengthen it, and to fillthe space between the frameG and the wheel F Both rollers have slightly-grooved surfaces,

whereby the corners of the blanks are rounded for the purpose of avoiding the formation of ridges or ragged edges during the finishing operation. The blanksm leave the rollers F and H in a horizontal direction along a horizontal guide-arm, g, which extends between the flanges h h, and causes the blanks to leave the said flanges and move toward the feed. roller I. The feed-roller I is a roughened surfaced roller, and is connected with a pinion, 1 which receives its motion from the wheel F by means of an intermediate gear, 1 Be 'In the accompanying drawings,.A repre- I and prevented from downward motion.

- as'fast as cast-iron.

tween thefeed-roller I and its pinion a pivoted plate, J, is fitted loosely upon their con mon shaft 6. The said plate J has a vertical slot, j, and a flaring lip,j, which latter serves to readily take up any laterally-bent blanks theend of a spring, I, so that its shaft 2" can travel freely up and down in the slot j, and

- thus adapt itself to varying thicknesses of the blanks, and at the same time, by the power of the spring 1 insures the said blanks against I slipping on the feed-roller. The said wheels I l and I are attached to an extension, G, of

the frame G. There is also a small guideblo'ck, 9, between the feed-roller and the wheel D, whereby the blank tr is supported The blank ismoved upon 'the wlieel'D, and settles upon the bending-rollers k M. The wheel D is provided with a very strong rim, d,and web (1. The rim d has a number of die-plates,

K, inserted inits face. .Thesaid die-plates have openings corresponding in size and shape with the outside of a finished horseshoe. A

continuous hollow steel die, K,-is, by means of a tapering fit or joint, firmly inserted from below into the described opening of'the dieplate K, with which its upper surface forms a step of the depth of the intended horseshoe. .The inside of the said steel die forms a line very nearly'concentric with the outside, and about midway of the breadth of the horseshoe. The opposing inner sides at the right and left of the steel die K are provided with raised knife-edges W, and nail-hole punches.

k, which serveto provide the horseshoe with the side creases and the marks for the nailholes. The space'inside of the steel die K is occupied by a movable die, L, which has-a projection for forming the inside of thehorseshoe,.and a step, l, which, in its normal p0- sition,.is flush with the main surface of the steel die K1, and represents the complementary width of the bottom face of the horseshoe. The curved part of said projection of the movable die is, by'preference, a piece of hardened iron or steel, 1, which does not wear The said front piece I and the die L- are fastened to a shank, L, which is fitted by means of a dovetail or groove and tongue, as seen in'Fig. 10, into the webof the wheel D in aradial direction.

The said shank L isprovided with a frictionroller, P, which, during the first part of the without jamming or catching against the sides of the horseshoe, lift it freely oif the die. The said stripping-plates N are fastened to '2' f I I 182.268

shanks or sheets N, which are attached to theframe A in a suitable manner. The distance between the plates N is such as to permit a free passage of the die L between them. Before the rollers l leave the guide-plate they are moved up toward the center of the wheel D, and the dies L are thereby moved completely within the circumference ofthe said wheel, thus stripping off the finished horseshoe, which, having been acted upon by the pressing-die of die-w heel D, falls to the ground.

The bending-rollers 7c 70 are pivotedto the arms 0 o of two sliding bars, 0 O, which are arranged in a parallel direction in a bearingbox, P, suitably fastened to the frame A.

The bar 0 extends to the 'outside'of the wheel C, where it has arm, 0 with a roller, 0, at its end,and the bar Oextends to the innerface of the wheel 0, where it has an arm, 0 with a roller, 0 at its end. The bar 0 has a stand,p and the arm 0 of the bar.() has a the rollers 70 I0 is strictly accordant with the outside shape of the horseshoe bent by the described motion around the die L.

A shield, P concentric to the periphery of the wheel l) upon the top of the bearing-box I P, prevents the horseshoe-blank from tilting while it is being bent, and an. arm, 1, fastened to. the same top prevents the blank from passing beyond its central position upon the wheel D before it is bent. The so-bent horseshoe is carried down by the die L, which, in so doing, is gradually drawn in by the guide M, followed in the latter movement by the horseshoe m, which is gradually depressed into the die-plate K by the shield Q, eccentric to the periphery of the wheel D, forming a lower extremity of the bearing-box P.

I The wheel (3 on the shaft B moves with the same speed as the Wheel 0, for reasons above stated, and, therefore, the die-wheel D is provided with an equal number of die-plates as the die-wheel D, which isdriven by wheel 0. And the die-plates R of the die wheel D are provided with raised horseshoe molds rand with pits T for the reception of the dies L on the. die-wheel D. The surfaces of the step I and thedie K being straight, the surface of the mold 'I is in a longitudinal direction, so

curved as to form, with the said opposing straight surfaces, in passing each, other, the desired thickness of a finished horseshoe.

The protruding knife-edges k and nailmoving the front corner k of the skeleton die p K. To prevent crowding ofthe metal around the nail-punches 70 and to facilitate the opening of the thereby-formed nailmarks, the

molds r are provided with notches 'r which serve to, provide the horseshoewith corresponding projections in line'with the marked nail-holes. The horseshoer can thereby easily adjust the horseshoe upon his swage when he wants to punch the nail-holes through, and thereby secure straight holes and save his drift from bending or upsetting upon the swage or anvil face.

Operation The laborer receives a raw iron bar, heated in a furnace to a degree necessary for light forging, and places its end upon the roller F right against one of the cutters f. The rollers F H impinge upon the bar, draw it inbetween them, and give it the form above described. The so-rolled part is then separated by the next knife f, and passed over to the' feed-roller I, which, by aid of the pressure-roller 1 delivers it upon the wheel D and the rollers 70 k, the arm P stopping its progress beyond: the right limits, and

the concentricshield P? preventing its revolving. Shortly after one of the dies L, being sufficiently elevated by the guide M, strikes the said blank in the middle, and the depressions c on the rim of the wheel 0 permit the rollers his to move apart and together again-in such manner as to firmly bend the so-caught blank :0 around the die L. Upon further progress of the rotation of the wheel D the die L is drawn within the die-plate K, and the horseshoe is gradually forced into its recipient opening in the dieplate. Right after the said operation the dieplates K and R meet together, the die L en ters the pit r, and. the horseshoe is pressed, by the raised mold 7', against the stop 1, the skeleton die K, the edges I0 and punches k whereby its form isfinished. now, by means of the roller l on its shank L, and the rim projection of the guide M, pushed out until the finished horseshoe is beyond the surface of the die-wheel D, at which instant the plates N enter between the said horseshoe and the wheelD. When the plates N are nearly passed the die is, by means of the projection m on the lower rim ofthe guide M, drawn back, and freed from the horseshoe, which is held down by the plates N, and finally dropped. The iron bar is very quickly taken up bythe rollers F H, so thatithas are, in section, of trapezoidal form, or with one edge thinner than the other, the thin edge being at the inside of the horseshoe.

Having, described my invention, what I claim, and desire tosecure by Letters Patent,

1. In a horseshoe-machine, the rollers F and H for shaping and cutting the blanksfor horseshoes, substantially as hereinbefore set forth.
